INGOT-POURING MECHANISM.

Application filed February 11, 1920.

T 0 all whomz't may concern Be it known that I, SAMUEL B. SHELDON, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Ingot-Pouring Mechanism, of which the following is a specification.

This invention relates to ingot pouring mechanism.

One object of the invention is to provide improved means whereby one or more ingots may be poured at a time, and whereby the flow of the molten metal to one or more ingot molds may be controlled in a simple and eflicient manner.

Another object is to provide simple and efficient means whereby the length of a plurality of ingots being poured may be equalized and whereby selectively one, two, three, four or more ingots may be poured at a time.

Another object is to provide simple and efficient ingot pouring mechanism wherein the parts cooperate to meet the various requirements for successful commercial operation. 4

These and other objects are accomplished by means of the ingot pouring mechanism rangement;

Flg. 4 is a detail sectional view taken in the plane of line 4-4 of Fig. 2; and,

Fig. 5 is a longitudinal sectional view of one of several stoppers which form a part of the mechanism.

The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

It'may be stated preliminarily that the pouringmechanism is located below a casting ladle which receives its charge of molten metal from an open hearth furnace, or any other suitable source, said ouring mechanism also being located a ove the ingot Specification of Letters Patent.

molds into which the molten metal is to be poured, the primary function of the ingot pouring mechanism being to subdivide the single stream of molten metal which issues from the casting ladle into a plurality of streams directed into the underlying ingot molds, the flow of molten metal being controlled in a manner whereby the streams of metal may be poured into one or more of a plurality of ingot molds and wherebywhen a plurality of streams of molten metal are directed into the underlying ingot molds, the relative quantity of flow may be accurately controlled. The pouring mechanism, which is interposed between the casting ladle and ingot molds, is movable along a pouring platform to locate same over any group of molds, and is also adjustable in the other direction transversely of the pouring platform and with respect to the casting ladle and the ingot molds for securing the proper relative positioning of the members in question.

Referring to the figures of the drawings, it will be noted that I have shown a casting ladle 10 which, as stated above, may receive its supply of molten metal from any suitable source, said casting ladle having an outlet nozzle 11 which, when the parts are in operative position, is located over a primary pouring trough or box 12 having a plurality of nozzles 13 and 14 through which molten metal may pass'into two secondary pouring troughs or boxes 15 and 16,each of which has two nozzles, the nozzles 17 of pouring trough 15 in the arrangement shown being located over ingot molds 18, and the nozzles '19 of pouring trough 16 being located directly over the ingot molds 20. As is usual, the ingot molds are mounted upon cars 23 and 24 movable on tracks 25 located below and adjacent the pouring platform 26 having tracks 27 upon which a truck 28 may travel lengthwise of the pouring platform, said truck 28 bodily carrying all of the pouring mechanism, which is located intermediate the casting ladle and the ingot molds. The secondary pouring troughs, and also the primary pouring trough, in each case are carried at the end of a lever or rod 29 which is movable transversely of the truck and of the pouring platform for adjusting the troughs laterally with respect to the pourin platform, ingot molds and casting ladle. lFor making this adjustment I have provided the rods 29 in each case with a lever 30, the lower end of which is forked to receive between the legs 31 thereof the associated rod 29, the rod 29 and legs 31 of the lever being pivotally connected to each other by a pin 32 extending through the parts in question. The lower ends of the legs 31 are pivotally connected to frame members 33 of the truck by a pin 3a which acts as a fulcrum about which the lever 30 swings, wherebythe rod 29 in each case may l e moved inwardly and outwardly for the purposes described. In each case the rod 29 is supported on the truck by a roller 35 mounted over the rod at the rear side of the truck and by a roller 36 mounted under the rod 29 at the front side thereof. The front end of the lever to which the primary trough is attacl ed is bent upwardly for positioning the primary trough 12 under ladle nozzle 11 and over the secondary pouring troughs 15 and 16. In this connection it will be noted that the primary pouring trough is triangular in plan with one corner of the trough being presented under the ladle nozzle 11. Also it will be noted that the secondary pouring troughs are triangular in shape and that the nozzles 13 and let of the primary trough are located over adjacent corners of said secondary pouring troughs. In this way the lengths of the troughs are reduced to a minimum and at the same time the point of introduction of the molten metal into each trough is spaced from the outlet nozzles of each trough.

As mentioned hereinabove, it is desirable to control the flow of the streams of molten metal from the primary pouring trough into the; secondary pouring troughs, and from the secondary pouring troughs into the underlying ingot molds. To accomplish this function I have provided a plurality of stoppers 37 which are supported at the ends of levers 38 and 39. The levers 38 are fulcrumed upon rollers 40 mounted on brackets 41, which are secured to a protecting plate 42 mounted on the truck, and the levers 39 likewise are fulcrumed upon rollers 43 mounted upon brackets n secured to the same protecting plate 4-2. As shown in the figures of the drawings, the stoppers 37 are in positions closing nozzles 13, 14, 17 and 19. It is apparent that if it is desirable to have the molten metal, which flows from the casting ladle 10 into the primary pouring trough 12, divided into four streams for pouring four ingots, all of the stoppers 37 will be raised by pushing downwardly upon the free ends of the levers 38 and 39. However, if it is desirable to pour but two ingots, for example, into molds 18, only one of the stoppers of the primary pouring trough would be raised, whereupon a single stream of metal would flow from said primary trough into only one of the secondary troughs, from which two streams of molten metal would flow it both of the stop pers in the particular secondary trough were raised. If, however, it was desirable to have but a single stream of molten metal flow from a secondarytrough, only one of the stoppers therein would be raised. From this arrangement it is perfectly obvious that the relative rates of flow of the molten metal through the nozzles of the primary trough may be controlled by the degree of opening provided by raising the associated stoppers the desired amount, and likewise the relative rates of flow through the nozzles of the secondary troughs ma be controlled in the same manner. It will be noted that in each case the primary and secondary pouring troughs are not tilted and that the control is effected entirely by raising and lowering the stoppers. By means of this pouring mechanism a simple and ellicient arrangement is provided for controlling the relative rates of flow through the nozzles of all of the pouring troughs in a manner to meet all of the requirements for successful commercial operation.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claim:

1.
